1-4 Carbon Atoms = Gas

5-14 Carbon Atoms = Liquid

15+ Carbon Atoms = Solid

Alkanes and Alkenes are insoluble in water,but are soluble in nonpolar solventsinstead.

As the number of carbon atoms increase,so does themelting and boiling point of the alkane/alkene this is also aresult of the increased Van der Waals forces betweenmolecules.

Alkanes and Alkenes do notconduct heat or electricity well.
